Emergency backup power supply
Battery Replacement Instructions
GE Simon 3 System
Those residential security system have a backup battery designed to supply power to the security system during a limited
power outage. The battery must be replaced from time to time due to age and usage. The backup battery needs to be
replaced when the keypad displays a "BAT" or "SYSTEM LO BATTERY" message.
In most cases you can replace the battery yourself, typically saving you time and money. The process requires the removal
of two wires from the old battery and reconnecting the same wires to the new battery. Before replacing the battery, please
read instructions carefully, including the Battery Safety Warning instructions on page 2.
